Summary: CachingMemorySSAWalker::invalidateInfo was using IsCall to determine which cache map needed to be cleared of entries referring to the invalidated MemoryAccess, but there could also be entries referring to it in the other cache map (value entries, not key entries). This change just clears both tables to be conservatively correct. Also add a verifyRemoved() function, called when expensive checks (i.e. XDEBUG) are enabled to verify that the invalidated MemoryAccess object is not referenced in any of the caches.
